Definitions

  • Grass lawns and turfgrass are dominant landscape features of many residences and commercial properties. Turfgrass are also increasingly prevalent in gardens and recreational areas, such as golf courses. Given the high visibility of these recreational, residential, and commercial areas, maintaining the color, uniformity, and durability of grass is of continued importance.
  • a wide variety of grass such as turfgrass, is susceptible to unwanted vegetation, such as annual and perennial grass weeds, sedges and kyllingas, and broadleaf weeds, that negatively influences both the quality and durability of the grass.

  • the weeds detract from the beauty of lawns due to the contrast in color and texture between the desired grass plants and the weeds. Consequently, weeds detract from the uniformity of a turf and add to its maintenance requirements. In addition, the weeds compete with the desired grass plants for available water and nutrients, usually resulting in thinning of desirable plant cover.
